How to disable Google Home suggestion to add a flow card to say something back

I have google home successfully integrated with Homey. I can start flows seamlessly by talking to Google Home as much as I want.
Now Google keeps on suggesting that I can add a flow card ’say something’ to be able to talk again in the same flow.
(In dutch: je flow is gestart je kunt zeg eens kaartje aan je flow toevoegen om…)
I don’t want this!

Any clue how I can turn it off?
